American on journey no longer anchored (5)
I believe the answer is:
atrip
'no longer anchored' is the definition.
The answer and definition are not the same part of speech. However, past participle verbs and adjectives occasionally mean the same thing.
'american on journey' is the wordplay.
'american' becomes 'a' (common abbreviation - e.g. in organisation names).
'on' is a charade indicator (letters next to each other).
'journey' becomes 'trip' (trip is a kind of journey).
'a'+'trip'='ATRIP'
Can you help me to learn more?
(Another definition for atrip that I've seen is " just out of bed".)
